Tension in a ropa to form transverse waves

[MissEuropa]

Homework Statement

With what tension must a rope with length 2.20m and mass 0.100kg be stretched for transverse waves of frequency 43.0Hz to have a wavelength of 0.700m?

Homework Equations

No idea

The Attempt at a Solution

I am completely oblivious as to where to start this question. I always like to have an attempt at a solution when I post, unfortunately I don't know where to begin.
Any help with relevant equations would be greatly appreciated as my physics class has yet to cover relation between tension and transverse waves.

After some rooting around and Wiki (how I love Wiki) I found that:
v=√T/μ
Where μ is mass per unit length.
v=λf
I plugged in the values for λ (wavelength) and f (frequency) to solve for velocity.
Then I symbolically solved the first equation for T:
T=v²*μ

And BAM I got tension.
Hopes this helps anyone else with this same problem :-)
